   6           Stores not just filenames but the files themselves in a balanced
   7           tree.  Uses journalling.
   8
   9           Balanced trees are more efficient than traditional file system
  10           architectural foundations.
  11
  12           In general, ReiserFS is as fast as ext2, but is very efficient with
  13           large directories and small files.  Additional patches are needed
  14           for NFS and quotas, please see <http://www.namesys.com/> for links.
  15
  16           It is more easily extended to have features currently found in
  17           database and keyword search systems than block allocation based file
  18           systems are.  The next version will be so extended, and will support
  19           plugins consistent with our motto ``It takes more than a license to
  20           make source code open.''

  26           If you like it, you can pay us to add new features to it that you
  27           need, buy a support contract, or pay us to port it to another OS.

  29 config REISERFS_CHECK

  31         depends on REISERFS_FS
  32         help
  33           If you set this to Y, then ReiserFS will perform every check it can
  34           possibly imagine of its internal consistency throughout its
  35           operation.  It will also go substantially slower.  More than once we
  36           have forgotten that this was on, and then gone despondent over the
  37           latest benchmarks.:-) Use of this option allows our team to go all
  38           out in checking for consistency when debugging without fear of its
  39           effect on end users.  If you are on the verge of sending in a bug
  40           report, say Y and you might get a useful error message.  Almost
  41           everyone should say N.

  43 config REISERFS_PROC_INFO
  44         bool "Stats in /proc/fs/reiserfs"

  46         help
  47           Create under /proc/fs/reiserfs a hierarchy of files, displaying
  48           various ReiserFS statistics and internal data at the expense of
  49           making your kernel or module slightly larger (+8 KB). This also
  50           increases the amount of kernel memory required for each mount.
  51           Almost everyone but ReiserFS developers and people fine-tuning
  52           reiserfs or tracing problems should say N.
  53
  54 config REISERFS_FS_XATTR
  55         bool "ReiserFS extended attributes"
  56         depends on REISERFS_FS
  57         help
  58           Extended attributes are name:value pairs associated with inodes by
  59           the kernel or by users (see the attr(5) manual page, or visit
  60           <http://acl.bestbits.at/> for details).
  61
  62           If unsure, say N.

  67         select FS_POSIX_ACL
  68         help
  69           Posix Access Control Lists (ACLs) support permissions for users and
  70           groups beyond the owner/group/world scheme.
  71
  72           To learn more about Access Control Lists, visit the Posix ACLs for
  73           Linux website <http://acl.bestbits.at/>.
  74
  75           If you don't know what Access Control Lists are, say N
  76
  77 config REISERFS_FS_SECURITY
  78         bool "ReiserFS Security Labels"
  79         depends on REISERFS_FS_XATTR
  80         help
  81           Security labels support alternative access control models
  82           implemented by security modules like SELinux.  This option
  83           enables an extended attribute handler for file security
  84           labels in the ReiserFS filesystem.
  85
  86           If you are not using a security module that requires using
  87           extended attributes for file security labels, say N.
